When a measurement tool consistently measures the same construct across different subgroups (e.g., racial groups), this property is called:
Answer: Measurement invariance
Measurement invariance confirms that a scale functions equivalently across different groups, enabling fair comparisons.
In ethics of research, the Belmont Report principle of justice primarily requires that:
Answer: Research benefits and burdens be distributed fairly across populations
The justice principle mandates equitable selection of research participants so no group bears disproportionate research burdens.
A researcher finds that a new assessment tool correlates highly with an established gold-standard measure of the same construct. This supports:
Answer: Concurrent criterion validity
Concurrent criterion validity is established when a new measure correlates strongly with a recognized criterion measured at the same time.
In meta-analysis, publication bias occurs because:
Answer: Studies with significant findings are more likely to be published than null findings
Publication bias inflates meta-analytic effect size estimates because non-significant results often remain unpublished.
An ANCOVA (Analysis of Covariance) is used to:
Answer: Control for a continuous variable while comparing group means
ANCOVA statistically controls for covariates to reduce error variance and produce cleaner group comparisons.
A rehabilitation researcher randomly assigns clients to two counseling approaches and measures outcomes. The primary advantage of random assignment is that it:
Answer: Controls for known and unknown confounding variables
Random assignment distributes both measured and unmeasured confounds equally across conditions, isolating the treatment effect.
Which qualitative approach uses in-depth interviews to explore the lived experiences of individuals with a shared phenomenon, such as acquiring a physical disability?
Answer: Phenomenology
Phenomenology focuses on describing the essence of a shared lived experience from the participants' perspectives.
